This Book is a study which includes environmental planning and education in the field of drinking water sustainable development. The book is based on the European Union Erasmus+ Project "Implementation of ECVET for Qualification Design in Drinking Water Treatment Plants and Sanitation for Pure Drinkable Water - PureH2O". In the 9th development plan (2013-2020) of Turkey, one of the development axes in its main objectives is protecting the environment and improving the urban infrastructure. The rationale of the project is enhancing the quality and performance of VET system improving education in drinking water supply and development. It can be achieved through promoting creativity, innovation and transfer of EQF/NQF principles in education of the main target group in the sector. The project promotes application of instruments such as EUROPASS, EQF and ECVET. They all need to be tested on a broad basis at various countries and sectors in order to check their feasibility and practical application. This innovative practice is of mutual importance for Turkey and EC countries and is a complex one in respect to the type of the target professionals, working in this area.
